An annular covering 90, of asbestos and the like is located in the pocket 81, and is cemented in place by the asbestos cement that has passed through the openings 58, 59, 78 and 79.

Referring to Fig. 7 a valve is indicated at r 95 and the insulation casing is indica-ted having a pair of members 96 and 97 similar to 31 and 61. The heads 55 and 75 are dispensed with and a sleeve 98 with the kreturn bend 99 is formed with the members 96 and 97 to engage the valve 95.

Referring to Fig. 8 a forty-five degree elbow is indicated at 100. The casing comprises a pair of curved semicylindrical members 101 and 102 hinged to each other by w means of the hinge 103. End heads 108 similar to each other and similar to the ends heads 42 and 66 are provided for the members 101 and 102. A clamping band 110 similar to 45 extends from the member 102 and engages an opening 112 in the member 101 to clamp said members to each other. The member 102 lias formed therewith the supplementalk cylindrically curved portion 1,13 and the member 101 has formed therewith the supplemental cylindrically curved portion 114.

Various modifications may be made in the invention and the present exemplification is to be taken as illustrative and Vnot limitative thereof. Y

Having described my invention what I desire to secure by Letters Patent and claim 1. In an insulation casing the combination of a pair of semicylindrical portions, a

" hinge vconnecting the portions, a supplemental longitudinal cylindrically curved portion extending from each semi-cylindrical portion, said cylindrically curved portions adapted to collapse relatively to each other and covering said hinge in their collapsed position and means to clampthe pair of semicylindrical portions to each other.

2. In an insulation casing the combination of a pair of semicylindrical portions adapted to contain a heat insulating mate-rial, end heads for the portions forming pockets, said end heads having main openings and supplemental openings, said mainV openings adapted to have extending therethrough pipes extending from a fitting in the casing, said supplemental openingsadapted for the flow there through of a portion of the insulating material from the interior of the casing, a hinge connecting the portions, a' supplemental cylindrically f curved portion extending from each of said semicylindrical portions, said cylindrically curved portions adapted to collapse relatively to each other and covering said hinge in their collapsed position and means to clamp the pair of said semicylindrical portions to each other'.

3. In an insulation casing the combination of al pair of semicylindrical portions, a hinge connecting the said portions at one end thereof, a clamping band extending from the other end of one of said portions adapted to enter an opening extending through the other portion to clamp the portions together, said portions adapted to contain a heat insulating material to cover a pipe fitting, and end heads for the pair of semicylindrical portions having main openings for pipes to extend therethrough and supplemental openings for the iow of a portion of the insulating material therethrough, said end heads forming pockets adapted to support pipe coverings and said coverings cementing with portions of the insulating material that extends through said supplemental openings.

4. In an insulation casing the'combination of a pair of portions, a hinge connecting the portions, means extending from the portions of the casing covering said hinge and meansl to clamp the pair of portions to each other.

5. In an insulation casing the combination of a pair of portions, heads having each a main opening and supplemental openings formed with the portions, said heads forming pockets with said port-ions, a hinge connecting the portions, means extending from t-he portions covering said hinge, said casing adapted to enclose a pipe fitting and also enclosing an insulation material covering said pipe fitting and means to clamp the portions of the casing to each other, said pockets adapted to support pipe coverings.
